PSMJ data consistently shows that fewer than 30% of AEC firms have a written, funded, and legally binding ownership transition plan.
That leaves many firms with a significant amount of work to do before ownership can successfully change hands.
As Greg Hart, President of PSMJ Resources, explains:
"Contrary to what many believe, the root cause of failed ownership transitions isn't simply a shortage of willing buyers. Failure is often a result of starting the process too late, using a one-size-fits-all approach, or focusing too much on the financial side of transition."
Successful AEC ownership transition requires both generations to prepare. Current owners need a realistic path for transferring the value they have built, while future owners need the leadership experience, financial capacity, and client relationships necessary to carry the business forward.
For AEC principals on either side of that transition, these are also the issues at the center of PSMJ's Legacy by Design: AEC Ownership and Succession Strategies Workshop, taking place September 15–16, 2026, in Denver, Colorado.
Why AEC Ownership Transitions Fail
A well-structured AEC ownership transition requires a minimum of five to seven years. Yet many principals wait until they are only a few years from their desired exit date before putting a formal plan in place.
By then, the next generation may not be financially prepared to purchase the equity. The firm's valuation may not meet the outgoing owner's expectations. The buy-sell agreement may be outdated or nonexistent. Key client relationships may still depend heavily on the current principal.
For AEC firm principals and managing partners planning to step away within the next 10 years, the transition window may already be open. The same is true for next-generation leaders preparing to take ownership and the CFOs, COOs, and advisors helping guide the transition.
Most principals assume the details will work themselves out when the time comes. But preparing future owners, transferring client relationships and decision-making authority, establishing a defensible firm value, and determining how the next generation will finance the transition all take time.
Leadership Succession Is Not Ownership Transfer
Leadership succession asks who will run the firm. Ownership transfer asks who will own the equity.
Firms can have excellent next-generation leaders who are not yet financially prepared to buy out existing owners. It can also have financially capable buyers who have not developed the experience necessary to lead the firm independently.
PSMJ recommends identifying potential owners five to 10 years before the transition, progressively expanding their decision-making authority, deliberately transferring client relationships, allowing managed failures in a controlled environment, and evaluating their performance on business metrics rather than technical output alone.
4 qualities are important for transition-ready AEC leaders:
- Business acumen: Understanding revenue, utilization, multiplier, and what drives firm profitability.
- Client ownership: Developing independent relationships with fee-generating clients.
- Team building: Recruiting, developing, and retaining high performers.
- Strategic vision: Articulating where the firm should be in 10 years and why.
The goal is to prepare someone capable of carrying the firm forward when the current generation is no longer making the decisions. Legacy by Design builds on that process, helping AEC firms identify and develop future owners, navigate generational differences, and create a clear path for emerging leaders to step into ownership.
Buy-Sell Agreement: The Document Most Firms Get Wrong
A buy-sell agreement establishes what happens to an owner’s equity when they retire, become disabled, die, are terminated, or otherwise leave the firm.
PSMJ identifies six areas every agreement should address: triggering events, valuation methodology, payment terms, restrictions on transfer, non-compete provisions, and dispute resolution.
But even firms with an agreement in place can run into problems if it no longer reflects the business.
Consider a firm that established a book-value pricing formula 15 years ago and has since tripled its revenue. The agreement may still exist, but the valuation mechanism may no longer reflect the firm that is actually being transferred.
PSMJ recommends reviewing and updating the agreement every three to five years, as well as whenever the ownership structure materially changes.
At Legacy by Design, attendees go deeper into the agreements that protect both buyers and sellers, including common buy-sell mistakes, indemnification provisions, non-competes, and how to structure agreements that are fair enough for both generations to actually sign.
Financing the Transition: Who Pays, and How
Valuation establishes what the equity is worth. The buy-sell agreement establishes what happens when it transfers. Financing determines whether the transition actually happens.
PSMJ identifies three common approaches.
Seller-Carried Note: The selling principal accepts installment payments from the firm or buyer, typically over five to 10 years.
Firm-Funded Redemption: The firm redeems shares from operating cash flow, potentially supported by a sinking fund, stock redemption insurance, or a dedicated profit allocation.
Bank Financing: Buyers secure a term loan to finance some or all of the purchase price, accelerating the seller's payout but requiring the firm and buyers to qualify for financing.
Whichever structure a firm chooses, affordability matters.
PSMJ recommends applying the planned payment structure to the total equity price and determining whether buyers can service the debt from their anticipated compensation at a post-tax debt coverage ratio of at least 1.25x. If they cannot, the price may be too high, the payment period too short, or buyer compensation too low.
Valuation itself can also introduce costly mistakes. For example, a principal earning $400,000 when the market replacement cost for the position is $200,000 is reducing EBITDA by $200,000. At a 5x multiple, failing to normalize that compensation could mean a $1 million difference in transition value.
Executing the Transition: A 7-Year Roadmap
Ownership transition is not a single event. It is a multi-year process requiring deliberate sequencing, milestones, and accountability.
Years 1–3: Foundation Phase
Identify transition candidates and begin expanding their authority and client exposure. Engage a valuation advisor. Audit or create the buy-sell agreement. Establish a baseline firm value and set financial improvement targets.
Years 3–5: Development Phase
Formally transfer key client relationships. Execute minority equity transactions where appropriate. Finalize the buy-sell agreement. Design the financing structure with legal and tax counsel. Put the leadership succession plan in writing.
Years 5–7: Execution Phase
Finalize valuation. Execute the primary equity transactions. Activate financing. Announce the transition internally and externally. The selling principal begins formally withdrawing from day-to-day operations and primary client-facing roles.
Year 7 and Beyond: Stabilization Phase
Monitor buyout payment performance. New ownership begins strategic planning. The retiring principal honors non-compete and consulting arrangements while the firm focuses on staff retention and cultural continuity under its new ownership structure.
The roadmap reinforces an important point: the transfer of ownership is not where succession planning begins. It is the result of years of preparation.
